The invention discloses a full-metal dry-friction type three-way strong-impact-resistant isolation buffer. The isolation buffer takes an outer housing and an inner supporting barrel as fixed parts, and takes an upper sleeve as a movable part; a dish-shaped metal wire screen vibration damping component is arranged between the outer housing and the upper sleeve; while excited by external vibration, the isolation buffer provides vibration buffer effect in a vertical direction and a horizontal direction; a metal wire screen buffer component is arranged outside an inner supporting barrel and a bottom plate convex ring; while excited by outside intense impact, the upper sleeve is in contact with the metal wire screen buffer component to achieve the buffer effect in the vertical direction and the horizontal direction; and a spiral spring between a regulating bolt and a bottom plate provides effect of buffering and returning vibration isolated equipment. The vibration buffer can realize three-direction vibration isolation to bear strong impact vibration, and is suitable for an off-road vehicle or the vibration buffer field under an extreme working condition.
Description
technical field [0001] The invention relates to the field of mechanical vibration isolation and buffering, in particular to a three-way anti-strong impact vibration isolation buffer for on-board instruments and equipment of armored vehicles. Background technique [0002] With the continuous advancement of science and technology, the maneuverability of armored vehicles has been greatly improved. During the driving of armored vehicles, the vibration of various parts of the vehicle body caused by the engine and transmission system is relatively large, and its vibration frequency is mainly concentrated in the middle and high frequency bands; at the same time, the unevenness of the road transmits vibration excitation to the vehicle body through the action system, and The vibration frequency is mainly concentrated in the middle and low frequency bands. However, in addition to normal off-road driving, armored vehicles will also be used in extreme environmental conditions, such as ...
